Carry your passion for science in your pocket.

This laser-cut, laser-engraved, 0.5 mm enamel-coated stainless steel pocket ruler is designed for passionate scientists and engineers who may find themselves needing a quick straight edge, wondering what's next to Technetium in the Periodic Table, pausing to double-check the 6th significant figure in the speed of light or who somehow forgot the 42nd digit of pi.

Keep it in your wallet at all times so you're always ready to do some science!

Great!!

I chose this item because I like the back part. There are many formulas and constants on the back!! I always carry this with me with the 'The Pocket Chemist - Wallet Sized Chemistry Stencil, Ruler and Unit conversion Reference'.

Very handy when you can't be tied to your desk or a device

This is unique and excellent tool. I am a general chemistry lab instructor and I'm always getting asked question that require me to go look up basic information. This will live in my lab coat pocket so I will allways have it handy as I move around the lab from student to student.
